Police and medical experts are giving a simple piece of advice to bikers who don't wear protective clothing - use some common sense and protect yourself.
This advice follows a disturbing increase of motorcycle riders and their pillion passengers who are not wearing suitable clothing while out riding during the recent good weather.
Traffic Sergeant Sean Gray, of the force's Roads Policing Group, said: "Officers have seen people wearing only tee-shirts, shorts and trainers while out riding. When officers speak to motorcyclists, the riders have said that as they are riding carefully they won't come off the machine. No matter how careful they are, there is still the possibility of a biker losing control by slipping on spilt diesel or the bike hitting a pot hole.
"My colleagues and I have all seen far too many people with horrific injuries.
"While there is only a legal requirement to wear a helmet, I and every other traffic officer urge anyone on a bike to apply some common sense when out riding by wearing suitable clothing to protect themselves. It could save a lot of pain and mean they can enjoy another day's riding in the future."
Dr Nick Athey, Consultant in Emergency Medicine at South Tees Hospitals NHS Foundation Trust, said: "I am urging all bikers to make sure that they always wear suitable protective clothing.
"Wearing a crash helmet alone is not enough to prevent death and serious injury. Whilst it may be tempting not to wear suitable protective clothing in the hot weather, it is simply not worth the risk.
"Bikers and pillion passengers may suffer so much additional trauma that they do not even survive the initial collision as a result of wearing inadequate protective clothing.
"Without the right clothing the road surface will act like a cheese grater. The skin, muscle and even bone can be torn from the body leaving deep and dirty wounds which are incredibly painful and difficult to treat.
"The treatment for these preventable injuries may involve surgery and skin grafts followed by scarring and potential long term disfigurement."
